[PATCH v3 0/2] remove different PHY fixups - dts part

changes v3:
- split arch and dts changes

changes v2:
- rebase against latest kernel
- fix networking on RIoTBoard

This patch series tries to remove most of the imx6 and imx7 board
specific PHY configuration via fixup, as this breaks the PHYs when
connected to switch chips or USB Ethernet MACs.

Each patch has the possibility to break boards, but contains a
recommendation to fix the problem in a more portable and future-proof
way.

Latest kernel is actually using phy-mode property, so set proper value to make
fec interface work again.

Without SoC specific PHY fixups the network interface on this board will
fail to work. Provide missing DT properties to make it work again.

Applied both, thanks.
